چکیده

The yucca moths (Parategeticula Davis and Tegeticula Zeller; Lepidoptera: Prodoxidae) are known for their obligate mutualism with yuccas (Yucca: Agavaceae). Three new species of the previously monobasic Parategeticula are described from Mexico, and the genus is redescribed. The new species P. elephantipella, P. martella, and P. tzoyatlella share highly modiÞed nonpiercing ovipositors with P. pollenifera Davis, a synapomorphy within all Incurvarioidea. Phylogenetic relationships are discussed, with morphological apomorphies mapped. Evidence for early evolution of thedistinctive lifehabitsofParategeticula suggest that the interactionsbetween thesemothsand their hosts can provide insights into the origin and early diversiÞcation of the obligate mutualism.

Phylogeographic structure in the bogus yucca moth Prodoxus quinquepunctellus (Prodoxidae): comparisons with coexisting pollinator yucca moths.

The pollination mutualism between yucca moths and yuccas highlights the potential importance of host plant specificity in insect diversification. Historically, one pollinator moth species, Tegeticula yuccasella, was believed to pollinate most yuccas. Recent phylogenetic studies have revealed that it is a complex of at least 13 distinct species, eight of which are specific to one yucca species. ...

First Recorded Observations of Pollination and Oviposition Behavior in Tegeticula antithetica (Lepidoptera: Prodoxidae) Suggest a Functional Basis for Coevolution With Joshua Tree (Yucca) Hosts

Yucca moths (Tegeticula spp.) are the exclusive pollinators of Joshua trees (Yucca brevifolia s. l.). The moths actively pollinate the Joshua tree flowers and lay their eggs in the style. Recent studies have revealed that the plants commonly known as Joshua trees include two distinct, sister-species of plant: Yucca brevifolia Engelm. and Yucca jaegeriana McKelvey, each pollinated by two sister-...

The influence of interaction type and feeding location on the phylogeographic structure of the yucca moth community associated with Hesperoyucca whipplei.

The interactions between herbivorous insects and their host plants have been central in generating diversification in both groups. We used a community of four yucca moth species, monophagous on the host plant Hesperoyucca whipplei (Agavaceae), to examine how the type of interaction and where insects feed within a plant influence phylogeographic structure of herbivorous insects. These four speci...

Host specificity and reproductive success of yucca moths (Tegeticula spp. Lepidoptera: Prodoxidae) mirror patterns of gene flow between host plant varieties of the Joshua tree (Yucca brevifolia: Agavaceae).

Coevolution between flowering plants and their pollinators is thought to have generated much of the diversity of life on Earth, but the population processes that may have produced these macroevolutionary patterns remain unclear. Mathematical models of coevolution in obligate pollination mutualisms suggest that phenotype matching between plants and their pollinators can generate reproductive iso...

Examining genetic structure in a bogus yucca moth: a sequential approach to phylogeography.

Understanding the phylogeography of a species requires not only elucidating patterns of genetic structure among populations, but also identifying the possible evolutionary events creating that structure. The use of a single phylogeographic test or analysis, however, usually provides a picture of genetic structure without revealing the possible underlying evolutionary causes. We used current ana...
